ON/OFF Light Control
With the CFG DIP switch configuration shown in the figure above, the device does not send any DALI commands. Instead of that, the lighting is controlled by light outputs, LIGHT 1 and LIGHT 2, and the device operates in the ON/OFF light control mode.
In this control mode, it is possible to read or read/write the following Modbus registers, which can be found also in the DALI interface control mode:
- DALIX_ON_OFF_STATE, where X is the number of the light output (40254 bit 0, 40255 bit 0);
- DALIX_BROADCAST_LAST_SCENE, where X is the number of the light output (40254 bit 1, 40255 bit 1);
- DALIX_BROADCAST_OFF, where X is the number of the light output (40254 bit 2, 40255 bit 2).
The particular states of the light outputs are determined by means of physical motion sensor / presence detector (connected to special inputs) or switches (connected to digital inputs) in the same way as it is in case of the DALI interface control, but instead of sending DALI commands the device changes the state of the light outputs 1 and 2.
Monostable Switch Control
Monostable switches cause a short-time pulse, which closes the loop of the digital input. Depending on the actual state of the light output X, a single pulse on the digital input X opens or closes the circuit in the light output X:
- Circuit close (ON) is recalled if the light output X is open (OFF) and the raising edge of the signal on digital input X is detected.
In such case, the DALIX_ON_OFF_STATE register is set to 1 (ACTIVE).
- Circuit open (OFF) is recalled if the light output X is closed (ON) and the raising edge of the signal on digital input X is detected.
In such case, the DALIX_ON_OFF_STATE register is set to 0 (INACTIVE).
Dimming/lighting up the ballasts in the ON/OFF light control mode is unavailable.
Bistable Switch Control
Bistable switches have two stable states. Depending on the actual state of the DALI Group Status X, changing using bistable switch state connected to the digital input X opens or closes the relay circuit in the light output X:
- Circuit close (ON) is recalled if the relay circuit is open (OFF) and the raising edge of the signal on the digital input X is detected.
In such case, the DALI X Group Status register is set to 1 (ACTIVE).
- Circuit open (OFF) is recalled if the relay circuit is closed (ON) and the raising edge of the signal on the digital input X is detected.
In such case, the DALI X Group Status register is set to 0 (INACTIVE).
Motion Sensor/Presence Detector Control
To activate a motion sensor/presence detector to the control algorithm the user needs only to connect the sensor to the one of the special input S1 or S2. By default, the special inputs work in normal closed mode (NC). In case there is a need to change the PIR working mode from NC to NO, the value of the SI1_PIR_TYPE register needs to be changed.
- If the motion sensor/presence detector connected to the special input X detects
a motion, and the DALI Group Status X is 0, the relay circuit of the light output X closes (ON).
The counter starts counting down the time stored in the SIX_DELAY_OFF_TIME register. If the time elapses, then the circuit of the light output X opens. Time counting can be interrupted by the detection of another motion, which results in restarting the time counter. In practice, it means that the time counting begins when the last motion detected by the motion sensor/presence detector disappears.
- In case if the DALI X Group Status is activated by the signal from the motion sensor/presence detector, it can be overridden by the signal from switch(es) connected to the digital input X.
The motion sensor/presence detector functioning can be activated again by another signal on the digital input X or by power supply reset.
It is possible to block the motion sensor/presence detector functioning by changing the state of the SIX_BLOCKING register bit to active. The function of deactivating
a motion sensor/presence detector can be useful if the motion sensor\presence detector cannot have any impact on the lighting, for example, after normal working hours.
Single motion sensor connected to one of the special inputs can control two light outputs simultaneously. In order to do so, the user needs to apply an appropriate CFG DIP configuration. For more details, please refer to chapter Multi Light Output Control.
Light Output Multicontrol
The device allows to control two light outputs, LIGHT 1 and LIGHT 2, simultaneously.
With a proper CFG DIP switch configuration, the user can control two outputs by only one special input and/or digital input in a freely chosen configuration. Both special inputs and digital inputs can control LIGHT 1 and LIGHT 2 together as a single group.
Control algorithm in case of using switches or motion sensors\presence detectors is similar as it is by using a single light output in the ON\OFF Light Control Mode.
- The device closes the circuit only in the light output with the DALIX_ON_OFF_STATE active (where X is a number of the output; one of the light output circuit can be already closed by switch).
- If the motion sensor/presence detector detects any motion, the device opens the circuit only in the light output with the DALIX_ON_OFF_STATE inactive and not overridden by the switch (where X is a number of the output, one of the light output circuits can be already closed or open by switch).
Example:
In the room there is one motion sensor/presence detector connected to the special input 1 and two switches, one connected to the digital input 1 and the other to the digital input 2. The motion sensor / presence detector should control two light outputs, light 1 and light 2, in a group and the switches should control each output separately. The CFG DIP switch configuration should be set as it is in the figure below:
